72mm Multi-Coated professional 3 Piece Lens Filter Kit (UV-CPL-FLD) For The Canon EF 20mm f/2.8 USM Lens with HeroFiber® Ultra Gentle Cleaning Cloth

This filter kit is designed for use specifically with the 72 mm lens . A filter is ideal for protecting your valuable lens from scratches and dust. -UV filter absorbs ultraviolet rays to produce crisp, clear photographs. -Circular Polarizing filter eliminates reflections from non-metallic surfaces, and increases contrast and color saturation -FLD filter helps balance light in outdoor situations or where fluorescent lights are used A UV filter is used to reduce UV rays from entering the lens and striking the film but will not affect color balance. It also protects the lenses from expensive front element damage which could be caused by dirt, knocks or scratches. A Polarizer is different than most filters in that it is composed of two pieces of glass, mounted independently inside a round frame so that one can be rotated relative to the other. As it is rotated, it increasingly cuts out glare and haze. It removes unwanted reflections from non-metallic surfaces such as glass, water etc. and enables the colors to become more saturated, appearing clearer with better contrast especially in blue skies and white clouds. A FLD filter (fluorescent light correction) provides the perfect solution for obtaining pleasing skin tones and correct color while shooting without a flash under fluorescent lighting. This filter gives true-to-life color rendition by removing the harsh yellow-green cast ordinarily resulting from fluorescent bulbs. When shooting under natural light, a fluorescent filter dramatically increases color saturation of subjects such as sunrise and sunset. Works with any 72 mm lens! Lifetime warranty!
